What's new in 2026.0

Announcements

• New and updated features for this release are marked with in the online help. Also, use the search term "2026.0" to find the help topics that correspond to the changes and new features.
• Find the download of the new version in your Autodesk Account at https://manage.autodesk.com/ or through the Autodesk Access desktop application.
• Important: This is a major release. If you have been running Netfabb and/or Local Simulation on a network license, you must perform additional updates when updating to 2026.0:
  • Update Autodesk Network License Manager. Download it from https://knowledge.autodesk.com/customer-service/network-license-administration/get-ready-network-license/download-the-network-license-manager.
  • Generate a new network license file. Visit your Autodesk Account page at https://manage.autodesk.com/, find the new version of your product, and follow the link Generate network license file for your product. Then install this license file in the newly installed network license manager.

  Refer to this article in the Netfabb installation supplement help for more details.

• Netfabb Premium is now officially called just "Netfabb" and is available as Autodesk Fusion with Netfabb.
• With the 2026.0 release, Netfabb Ultimate has been retired.
  • There is no Netfabb Ultimate 2026 to download or update or upgrade to.
  • Users with a running license for Netfabb Ultimate can continue to run release version 2025.1.
  • Netfabb Ultimate licenses are not available for renewal anymore.
  • To benefit from continued updates switch to using Netfabb (formerly "Netfabb Premium") which has had most features previously reserved to Ultimate added with release version 2025 in April 2024.
  • This also effectively retires Selective Space Structures (3S) as well as Optimization Utility and Lattice Topology Utility.
• Read on below for a selection of highlights of this release. For more details on changes, fixes, and known issues, refer to the Release notes section of this online help.

Netfabb

1. Machine support

   • New workspaces for Aconity3D, Farsoon, Formlabs, HP, Photocentric, SCANLAB, Schaeffler Special Machinery, Stratasys, and Weirather machine models have joined Netfabb's extensive cover of options available on the market.

2. 3D and 2D packing

   • True Shape packing is a completely new development. Modern, fast, highly configurable, and designed and built with production-level additive in its focus. Uniquely, it natively handles duplication as well as distribution of parts and part copies to as many buildrooms as needed for covering the entire build job.

3. Reporting and automation

   • Covering every unique requirement for reporting would be nice, is but hardly realistic. Build job reports that itemize parts in particular open themselves to countless permutations of what should go into a report and where and how and when. Which is why we continue to trust our Lua automation to be the tool of choice for adapting to individual demands and gave it new methods to generate and serialize image data (think screenshots) to better serve database-based systems via ODBC connection. After all, those in turn can provide the task-oriented flexibility that has always been Netfabb's mission statement, and not just for document generation.

4. Supports

   • Several new support action and support geometry parameters help with printability:
     • Rotate the entire grid of bar supports on areas, not just the hatches themselves, to keep them in line and save time otherwise spent on beam repositioning
     • Prevent bars from turning too much towards the horizontal and becoming unprintable
     • Bias the cluster detection away from perfectly vertical so that accounting for anisotropic recoater effects no longer requires excessively generous overhang handling in all directions
     • Fill in unnecessary gaps in base plates generated from part shadow to make them more rigid and more easily to remove as a whole piece
   • Usability when working with supports has also received attention:
     • Invert the selection of supports with a simple command and keyboard shortcut
     • Search support action parameters by name

5. General UI improvements

   • The settings, too, received a search function to give the scroll wheel a break. Search works in the current language and narrows down results as more characters are typed.
   • Parts names may now also be searched for in the selection by property.
   • With functions like True Shape packing happily generating platform copies the project tree can get unwieldy. To help out there is now a new command to collapse all open nodes at once. Another command expands them all.
   • Slice analysis, the graphing of area occupied by contours along the Z axis, is now available universally for all part platforms and machine workspaces.

Local Simulation

Several new cards for setting up a simulation have been added to provide more realistic, elastic fixation of the build substrate and to make ghost part generation ignore temperature excess in supports and only concentrate on part geometry.

Advanced Toolpath Utility

ATU's JavaScript engine has been upgraded to V8. This brought, among other things, a profiler to the ATU IDE, helpful for analyzing code for bottlenecks.

Also now available is a JavaScript outline display that lists declared variables and defined functions for quick navigation. Enable it from the View menu. Profiling data is displayed in the Profiler results panel. This data can be the current build configuration and style but also saved data from a previous run, making it easy to compare and to check whether a code change helped, did nothing, or made things worse.
